DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 475,105, dated May 17,1892- Application filed March 12, 1892. Serial No. 424,695. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES BEW, a citizen of the United States,residing at Angola, in the county of Steuben and State of Indiana, haveinvented certain new and useful 1mprovements in Door-Checks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to door-checks which are designed in theirconstruction to hold the door open at any required angle against acurrent of air from any direction.

The object of the invention is to secure a door in the aforesaid mannerand admit of its being opened or shut by a person passing in or outwithout changing the tension of the check or holder. I

A further object of the invention is to vary the tension of thefastening devices, whereby the check or holder may serve in a measure asa lock to secure the door from being opened when closed.

The improvement consists of the novel features and the peculiarconstruction and combination of the parts, which will be hereinaftermore fully described and claimed, and which are shown in the annexeddrawings, in which Figure l is a perspective view of a door, showing theinvention applied thereto. Fig.

. 2 is a cross-section of a portion of the doorframe and the door at apoint corresponding with a central longitudinal line of the check Fig. 3is a perspective view of the check or holder detached from the door, theparts being separated and arranged in their relative position. Fig. 4 isa view showing the application of the invention to a windowsash forholding the same at the required elevation. The door A and the frame Bare of wellknown construction, the door being hinged to a side of theframe in the usual manner. The rod 0 is in axial line with the pin-tlesof the hinges of the door, and in the present case is secured to thedoor-frame, being preferably the cross-bar of a loop, which is providedat the outer end of a casting or plate which is let in a recess in theinner side of the doorframe. so as to come flush with the sitPe thereof.This rod is round in cross-section and is designed to be gripped by theholder on the door. The holder is composed, essentially, of bar D, leverE, somewhat shorter than barD and pivoted to the latter near thegripping end, and a tension device, as the thumb-screw F, whichiscarried by the bar D and adapted to press on the inner end of lever Eand cause the jaws d and e of the bar D and the said lever E,respectively, to grip the rod C. The jaws dand e have correspondinggrooves in their opposing faces to receive the rod 0. The bar D isdesigned to be fastened to the door in such a manner that the grooves inthe said jaws of the holder will coincide with the position of the rod0. The bar D is recessed on the side designed to come opposite the doorto receive the rear end of the lever E, which latter is concealed andguided in its movemen ts thereby. The parts being disposed, ashereinbefore stated, obviously to secure the door at the requiredposition, the thumb-screw F is turned in, which causes the jaws of theholder to grip the rod (3. The tension of the grip is varied by turningthe screw F in more or less.

An obvious application of the invention is shown in Fig. 4, in which arod G is attached to the casement of a window and the holder to a sash.When the thumb-screw is loose, the sash can be moved up and down; butwhen the sash has been brought to the required position it is fastenedby turning the thumb screw in, which causes the jaws of the holder togrip the rod 0.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, is

1. The combination, with a rod secured to one of the two parts to berelatively secured in a fixed relation,of aholder fastened to the otherpart and composed of abar which is recessed on its inner side, a leverpivoted to the bar and located within the said recess, the jaws of thesaid bar and the lever being constructed to grip the aforesaid rod, anda tension device carried by the said bar and adapted to effect agripping of the jaws on the said rod, substantially as and for thepurpose described.

2. The combination, with a rod secured to ried by the said bar andadapted to engage one of the two parts to be relatively secured with theinner end of the said lever to cause in a fixed relation, of a holderapplied to the the jaws to grip the aforesaid rod, substanother part andcomposed of a bar which is retially as described. I 5 5 cessed on itsinner side and having one end In testimony whereof I affix my signaturein extended and deflected and fastened to the presence of two witnesses.said part,a lever pivoted to the said bar near the free end thereof andhaving its rear end CHARLES extended within the said recess, the jaws ofl/Vitnesses; 10 the said bar and the lever being grooved to PHILIPWATERS,
